REFILL - Range: 0 to 155
This function allows the operator to adjust the
sensitivity of the refill circuit. This is mainly a trouble-
shooting feature. Water in different geographical loca-
tions can have different conductivities. By adjusting
the sensitivity of the refill circuit, this will allow the
brewer to operate under various water conditions.
Procedure to set the sensitivity threshold of the refill
circuit:
NOTE: Make sure the water in the tank is touching the
refill probe.
1. Press and hold the ® until the display reads SET
NEW RECIPES. Release the ®. Press and release
the ® pad until the display reads REFILL and
shows a number on both sides of the word.
2. To adjust the threshold setting, press (-) to de-
crease, or (+) to increase the setting.
NOTE: Always make sure that the number on the right
is larger than the number on the left when water is in
contact with the refill probe in the tank.
3. When finished, press and release DONE. This
saves the new setting and advances to the next
function screen, L SPRY OZ/M. Another alterna-
tive is to press and release either of the
located on the front switch panel to exit REFILL
and return to the MAIN SCREEN.
L/R SPRAY OZ/M
This function allows the operator to view or to
enter the actual flow rate coming out of the sprayhead
for each side of the brewer. This is NOT used to change
the actual flow rate, but to tell the internal controller
how fast the water is flowing. The unit of measure is
ounces per minute (OZ/M).
L SPRY OZ/M: XX.X
Procedure to adjust the flow rate setting:
1. Press and hold the ® pad until the display reads
SET NEW RECIPES. Release the ®. Press and
release the ® pad until the display reads L SPRY
OZ/M. The number represents what the brewer
thinks is the flow rate of the left side sprayhead in
ounces per minute (OZ/M).
2. If the actual flow rate of the sprayhead is known,
but is different than the number on the display, use
the (-) and (+) pads to enter the correct flow rate
in ounces per minute.
3. Press and release the ® pad until the display reads
R SPRY OZ/M and repeat 1 and 2 for the right side
sprayhead. When finished, press and release DONE.
This saves the new setting and advances to the
next function screen, L BYPS OZ/M. Another alter-
native is to press and release the
on the switch panel to exit R SPRY OZ/M function
and return to the MAIN SCREEN.

This function allows the operator to view or to
enter the actual flow rate coming out of the bypass
nozzle for each side of the brewer. This is NOT used to

measure is ounces per minute (OZ/M).
Procedure to adjust the flow rate setting:
1. Press and hold the ® pad until the display reads
SET NEW RECIPES. Release the ®. Press and
release the ® pad until the display reads L BYPS
OZ/M. The number represents what the brewer
pads
thinks is the flow rate of the bypass valve in ounces
per minute.
2. If the actual flow rate of the bypass valve is known,
but is different than the number on the display, use
the (-) and (+) pads to enter the correct flow rate
in ounces per minute.
3. Press and release the ® pad until the display reads
R BYPS OZ/M and repeat 1 and 2 for the right side
bypass valve. When finished, press and release
the DONE pad. This saves the new setting and
advances to the next function screen, CALIBRATE
